Issue/Introduction

• Adding a node to VCF operations through Fleet Management is stuck on Components 
• Warning in the UI shows 

  A Could not find the current component certificate. Use Fleet Management → Certificates to either add or replace the
  component certificate.
  
  Taking a snapshot is not required when adding a Cloud Proxy to an existing VCF Operations cluster. However, it is
  recommended when adding Replica, Data nodes. The snapshot operation will take the cluster offline, nodes will be
  powered off and then powered back on.

• Upgraded Aria Operations from 8.18.x to VCF operations 9.x
• Replaced the VCF operations certificate as per documentation Replace a Certificate with a CA-Signed Certificate but the certificate was not in use in Fleet Management for the VCF operations component
